Auto mak­ers are encour­aged by the lat­est hous­ing indi­ca­tors. In June, the rate of new-home con­struc­tion rose to the high­est lev­el in four years, on pace for 760,000 on an annu­al basis. A con­tin­u­ing recov­ery in home con­struc­tion should trans­late into even faster growth in truck sales in the sec­ond half and in 2013.
